Gradle: output from dependant task not included in artifact

I use IDEA 2016.3.1.

Say, my project has a following structure:

test
   ejb
   ear

Here is build.gradle from ejb:

task har (type: Zip) {
    archiveName 'test.har'
    from sourceSets.main.output
}

jar {
    from har.outputs.files
}

Here is build.gradle from ear:

apply plugin: 'ear'

dependencies {
    deploy project (':ejb')
}

There is no test.har in the artifact created by IDEA (exploded or packaged), but the ear built by gradle contains one.

Is there any possibility to overcome this problem?
